目的探讨小型猪正常胰腺的MRI表现及其解剖学基础.方法对8头健康小型猪行MR扫描,观察胰腺的形态、大小及信号强度.然后开腹观察所有猪的胰腺形态、位置和毗邻,同时术中探查胆总管和胰管的开口.术后处死2头,完整取出胰腺供解剖研究.结果小型猪正常胰腺分左、中、右三叶,在MRI上均能清晰显示.整个胰腺T1加权像信号强度高于肝、脾,T2加权像信号强度低于肝、脾.MR胰胆管水成像未见胰管显影,但胆总管能清晰辨认.解剖发现胆总管开口在胃幽门稍下方的十二指肠上部,而胰管开口于胰右叶对应十二指肠内壁乳头.结论小型猪正常胰腺MR成像显示良好;解剖上小型猪胰腺形态和胰胆管汇入方式与人类有所不同.

Objective To observe the MRI findings of normal pancreas in piglets. Methods Eight healthy piglets underwent MR examination, and the morphology, size, signal intensity of pancreas were observed. After MR imaging, all piglets were abdominally incised to observe the anatomy of pancreas and pancreatic adjacent structures. The opening of both common bile duct and pancreatic duct were detected during operation. Two piglets were sacrificed after operation and the whole pancreases were dissected for anatomic research. Results The pancreas of piglets was composed of three parts: right lobe, median lobe and left lobe. All the lobes were displayed clearly on MRI. The signal intensity of pancreas was higher than that of liver and spleen on T1WI, whereas lower than that of liver and spleen on T2WI. On MRCP, pancreatic duct was not presented, whereas the common bile duct could be seen clearly. The opening of common bile duct located at superior part of duodenum (nearby the pylorus) and the opening of pancreatic duct situated at duodenal papilla corresponding to pancreatic right lobe. Conclusion MRI can show the pancreas of piglets very well. The morphology of pancreas and features of common bile duct conjunction with pancreatic duct in piglet are different from those in human.
